DEEP-WELL PUMP.

To all whom z't may concern:

Be it known that I, Lans lV. BoDiNsoN, a citizen of the United States, resid-ing at Aurora, in the county of .Kane and State of Illinois, have invented certain new and useful Improvements in Deep-fell Pumps, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to deep well pumps of the reciprocatory type and it has for its principal object the provision of a new and improved form and arrangement of parts by which a very great amount of water can be forced upward through a comparatively small bore. For the accomplishment of this purpose, have provided a stationary1 cylinder and three movable cylinders all in alinement with each other, threel plungers movable with said three movable cylinders, and three other plungers working in said movable cylinders, said three movable cylinders and their connected plungers being adapted to be reciprocated in unison by one pump rod and the plungers in the movable cylinders being adapted to be reciprocated in unison by another pump rod. It is one of the objects of my invention to improve the form and operation of pumps of this type in sundry detailsv hereinafter pointed out. The preferred means by which I have accomplished my several objects are illustrated in the accompanying drawings and are hereinafter sp-eciiically described. That which I believe to be new and desire to cover by this application is set forth in the claims.

In the drawings Figure 1 is a central vertical sect-ion through the upper part of the pumping apparatus located in the bottom of the well;

Fig. 2 is a central vertical section through the lower part of the pumping apparatus in the bottom of the well, being a downward continuation of the parts shown in Fig. l;

Fig. 2L1 is a diagrammatic view illustrating a form of driving meansadapted for reciprocating the pumprods in opposite directions; and

Figs. 3, to 11, inclusive, are horizontal cross-sections on the correspondingly-numbered section lilies of Figs. l and 2.

responding parts are indicated by the same reference characters,-

20 indicates a well tube, vto the lower end of which, lthrough the medium of a screwthreaded coupling device. 2l, is secured a stationary cylinder 22 preferably made of brass. A plunger 23 is adapted to be reciprocated, by the means hereinafter described, in the cylinder 22. A second cylinder 24 is connected at its upper end to the plunger 23, and a third cylinder 25 is connected to the lower end of the cylinder 2+ by means of a coupling member 26 which serves as a closure member for the upper end of the said cylinder 25 which is provided with an annular inlet opening for the cylinder 24. A fourth cylinderA 27 preferably made of brass, is connected to the lower end of the cylinder 25 by means of a member 28 which serves as a coupling, as above described, and also as a plunger as will appear hereinafter, serving also to provide an inlet port for both of the cylinders 25and 27. The lower end of the cylinder 27 is provided with a plunger 29 movable therewith.

In the cylinders 24, 25 and 27 are three plungers 30, 31 and 32, respectively, suitably connected together, as hereinafter described, and adapted to be operated in unison in the said'three cylinders. Y

Secured to the lower end of the stationary cylinder 22 and extending downward about the three movable cylinders serving as a suction pipe for the several plungers, is a pipe or tube 33, having connected to its lower end below the lowermost movable cylinder a valve-cage 34k provided with an upwardly-opening valve v35 of any suitable type. A lower suction pipe 36 extends downward from the valve 35 to' the limit of the suction power of the pumping apparatus, whereby the pump is prevented from suckino; air as the level ofthe water in the well is lowered by continued pumping.

The means for reciprocating the plun` gers 30, 3l and 82 in unison comprises a pump rod 37, having connected to its lower endV a. tubular pump rod section 38, such connection being effected by the use of a coupling 39 which leaves the upper end of the tubular pump rod section open. The plunger 30 is connected to the pump rod section 38 by means oi' a coupling sleeve 25S which serves as a stop tor limiting the upward movement oit the upwardly-opening valve 4() ot the said plunger. The plunger 3() is provided with packing ell of any suit able type bearing upon the inner tace ot the cylinder Connected to the plunger 50 and extending downward therefrom is another tubular pump rod section i2 which extends rthrough the coupling member 26, having packing i3 arranged in such coupling member thereabout. l-i coupling el .serves to connect the lower end oi' the tubular pump rod section ft2 with the plunger 3l, said roupling serving as a stop for limiting the upward movement ot' the upwardly-opening valve #i5 ot the said plunger 51. The plunger 3l is provided with packing i6 of any suitable type bearing upon the inner face of the cylinder Connected to the plunger 3l and extending downward therefrom is another tubular pump rod .section 14T, to the lower end of which the plunger 32 is connected. rlhe plunger is hollow7 communicating with the lower end of the pump rod section il, an upwardly-opening valve il-S being provided lior preventing the escape ot' water downward from the said pump rod section. Packing if.) is secured about the plunger 32 bearing on the inner face or' the cylinder' 2T.

'l` he means for reciprocating the movable cylinders and the plunger-s carried thereby comprises a tubular pump rod 50,110 the lower end olf which there is connected a large tubular pump rod section l which surrounds the coupling' member 39. rEhe connection between the pump rod 50 and the tubularl pump rod section 5l is eliiected through the use or' acoupling which provides a llarge annular opening from the said pump rod section into the well tube 20. The plunger is .:onnected to the pump rod sect-ion 51 by means ot a sleeve 53, suitable packing 5st being provided between said sleeve and the stationary cylinder The plunger .23 is also provided with suitable packing about the tubular pump rod section and is provided with an upwardly-opening valve of any suitable type. rl"he plunger 28 is provided with an upwardly-opening valve 5T and with suitable packing` :38 about the tubular pump rod section l?. T he plunger 29 is provided with an upwardly-open ing valve of any suitable type.

lilith the plunger rods 37 and 50 being reciprocated by any suitable means i'n opposite directions, the operation will be as Yliollows :llpon the upward movement of the pump rod 37 and the downward movement of the pump rod 50. the lower end of the cylinder 27 will be filled with water through the valve 59, while the water in the upper end ot the said cylinder Qi' will be forced 'through the valve 5T of the plunger 2S into the eylinffler L5 below the plunger 3l. it the same time the water in the cylinder 25 above the plunger 3l will be Jiiorced through the coupling iii upward through the tubular pump rod sections l2 and ir and delivered into the tubular pump rod section 5l above the plunger 23, constituting two quantities or' water delivered above the plunger 23, one quantity displaced by a full downward stroke of the closure member QG and the other displaced by a. lull upward stroke ol' the plunger' 3l. At the saine time the cylimler 2l: is being lilled with water below the plunger 30 through the coupling member Lo, while the water in the cylinder 2i above the plunger 30 is being forced upward through the valve 56 ot the plunger 23, constituting two additional quantities of water so delivered above the plunger i3, one ot' such additional quantities ot' water being displaced b v a lull downward stroke ol the plunger 225 and the other by a lull upward stroke ot the plunger 30. Thus four substantially equal quantities ot water are dclivered above the plunger while that plunger is moving downward a full stroke, leaving a net gain of three quantities actually raised.

Upon thc (flowuinuird movement ot the pump rod 37 and the upward movement ot the pump rod 50, the water in the lower end ot the cylinder 2'? will. be forced upward through the valve 18 ot the plunger 32 and thence upward through the pump rod sections l-T. inl-2 and 35S into the pump rod section above the plunge" 23, constituting two quantities of water delivered above the plunger one quantity displaced by a full downward stroke oi the plunger 32 and the other displaced by a tull upward stroke oli. the closure member 29. Brt the same time the upper end of the cylinder 2T is l'illed above the plunger through the combination ccuugliuel member and plunger 28. At the same time the water in the cylinder below the plunger fl passes upward through the valve ot the plunger 3l but still remains in the upper end oli the cylinder the valve 5T serving to prevent the water trom escaping vfrom the tube 1li. into the already lilled cylinder fit the ame time the water in the cylinder Q-Llbelow the plunger 230 passes upward through the vi lve r#t0 oli the plunger but still. remains in the upper end of the cylinder 2l. At the same time the water in the stationary cylinder :22 above the plunger 23 is forced upward bv a full upward stroke of the said. plunger 22%, Thus it will be seen that upon the downward movement of the prunn rod 3T and the upward movement of the pump rod 50. there have been two quantities ot water delivered above the plunger :[23 while that plunger was by a full upward stroke raisinganother quantity, making a total of three v quantities actually raised.

The torni of means shown for reciprocating the pump rods 37 and 50 in opposite directions comprises cross-heads (S0-(5l connected to said pump rods respectively, said cross-,heads being slidable vertically in suitable slots (S2- (53 provided by a frame 6. rlhe cross-heads GO and (il are connected by means of links with suitable offset portions of a crank-shaft 66 which is adapted to be driven from any suitable source of power by means of a drive-wheel G7.

It is thus seen that by my improved ariaiigeineiit of pluiigeis and cylinders, am enabled by the use of two puinp rods to raise six quantities ot water at each coinplete cycle of operation ot the pump rods, each ot such quantities of water being equal to the amount raised by an. operative stroke of a single plunger. lt will be seen that the amount of water raised upon the down stroke ot one pump rod is substantially the same as that raised upon the down stroke of the other pump rod. l have thus provided pumping means ot great etliciency, both as to the amount oi2 water capable of being raised and as to the balanced condition. which exists throughout the operation ot the pump.
